Patent DE-19755972-A1 (DE)
Title: Ring spinner or twister spindle
Inventor: ANDEREGG PETER
IPC: D01H9/16
Filed: 1997-12-16
Abstract: At the spindle of a spinning station, a blade (11) is between the underwinding crown (15) and the sliding sleeve (9).  It is positioned so that, when the yarn (45) is clamped between the underwinding crown (15) and the clamping surface (14) of the sliding sleeve (9), its path is deflected round the blade (11). The blade (11) is below the underwinding crown (15) and above the sliding sleeve (9).   The blade cutting edge (11') is aligned downwards and extends radially outwards from the clamping surfaces (14) at a sleeve section (15') or the sliding sleeve (9).  When the yarn (45) is clamped, or when the sliding sleeve (9) is closed, the cutting edge (11') of the blade (11) is below the clamping surfaces (14), and is further displaced from the cop than the clamping surfaces (14). The yarn (45) path, from the cop, is initially aligned downwards to the cutting edge (11') of the blade (11), and then moved upwards at an angle until it passes round the sleeve section (15') or spacer (22) at the spindle shaft.  The spacer (22) gives the underwinding of the yarn (45) away from the spindle shaft, at least in part. The blade (11) has a cylinder ring shape, with a cutting edge parallel to the spindle shaft axis.  The cutting edge is ground into a conical shape.  The blade (11) is loosely attached to the sleeve section (15') on the spindle shaft, to lie on its outer periphery.

The connector head comprises a tempered cast metal material and is bordered by side wall sections in the peripheral direction and by wall sections above and beneath it. The side wall sections include vertical outer surfaces that form one eighth of the periphery of a circular wedge bracket. The connector head is divided into top and bottom sections (44), between which is a perforated disc section (30) with a slot open towards the rod section mounting surfaces, for placing over a rod section. Wedge openings (157,152) are provided in the top and bottom connector head sections for receiving a wedge part (41) pushed through these openings and the disc to tighten the rod section and connector rod together. The mounting part of the connector head combines with the mounting surfaces, the slot-forming surfaces and the vertical outer surfaces around the wedge to form a restricted space. Independent claims are also included for four modifications of this construction.
